To further promote the reuse of reclaimed water for irrigation purposes, the rules that apply when reclaimed water is injected into a receiving groundwater that has 1,000 to 3,000 mg/L total dissolved solids are applicable to reclaimed water aquifer storage and recovery wells injecting into a receiving groundwater of less than 1,000 mg/L total dissolved solids if the applicant demonstrates that it is injecting into a confined aquifer, that there are no potable water supply wells within 3,500 feet of the aquifer storage and recovery wells, that it has implemented institutional controls to prevent the future construction of potable water supply wells within 3,500 feet of the aquifer storage and recovery wells, and that the recovered water is being used for irrigation purposes. The injection of reclaimed water that meets the requirements of this section is not potable reuse. This section may not be construed to exempt the reclaimed water aquifer storage and recovery wells from requirements that prohibit the causing of or contribution to violations of water quality standards in surface waters, including groundwater discharges that flow by interflow and affect water quality in surface waters.
